FLAVIUS IIAYOT, OF PARIS, FRANCE.

MOTOR-ENGINE.

SPECIFICATION forming part of Letters Patent No. 623,713, dated April 25, 1899.

Application tiled April l 3, 1 8 9 8.

T0 all wwnt t may concern:

Beit known that I, FLAVIUS HAY OT, a citizen of the French Republic, residing at 3 Cotlogon street, Paris,France, have invented certain new and useful improvements in motor-engines with four pistons acting directly on the driving-shaft by means of one crank only; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

The object of the present invention has reference to a motor-engine provided with four pistons, two ofwhich move in a vertical cylinder, which is reciprocated horizontally by the other two, the four pistons transmitting together the rotation to the driving-shaft by means of one crank only.

The annexed drawings represent as an example of application a gas-engine, in which- Figure l is a vertical longitudinal section, Fig. 2 a vertical cross-section, Fig. 3 a plan view, and Fig. 4 an elevation, thereof.

A is a frame supporting thel crank-shaft B in the bearings C. In this frame are fixed two standards, formed with two cylinders E and slide-guides F. Between the two standards D D and by means of the guides G and pistons H is suspended the movable cylinder J, in which are reciprocating two pistons K, rigidly connected togetherv by means of a transverse bar L. In the latter projects the pin of the driving-crank M. It results thereby that the two pistons K K transform their reciprocating movement into a rotating movement of the crank, at the same time causing the lateral movement of the cylinder J.

The driving fluid acts only on one surface of the pistons, while the other surface remains open to the atmosphere. The fluid for the pistons K K is admitted by means of admission-chambers N, through which it also escapes and which are located on and under the cylinder J, while the fluid for the pistons H arrives by opening O and escapes by opening P, located side by side in the cover, Fig. 4. One openin g Q, made in the wall of the cylinder J, permits the displacing of the latter on the driving-shaft C.

This machine arrangement with four pistons will chiefly iind its application where the Serial No. 677j490. (No model.)

work to be performed is liable to produce shakings or, as in gas-engines, where the explosions produce ram-blows.

The advantages of this new engine are numeroussuppression of the dead-points, simplicity of construction, the pistons acting directly on the crank, and little room required. For a gas-motor these advantages are very valuable, four explosions in succession being obtained, if desired, for each rotation of the crank. By their application to the gas-motors the gas arrives on the pistons K K by two of the chambers F F and escapes by the two others. The admission will thus take place on one side of the machine and the escapement on the other. In this effect the guides G are provided with holes, putting the chambers F F in communication with the chambers N N.

The supplying mechanism, as well as the regulating and igniting mechanisms, may be of any well-known system that will allow the four pistons to act successively and independently one from the other, while permitting the use of one or of several of them-that is to say, if desired the work can be done by one, two, three, or by the four cylinders, according to the quantity of work to be produced.

I claiml. In a multiple-cylinder explosive-engine, the combination of a supporting-frame, standards carrying guides at their upper and lower ends, horizontal cylinders mounted in said standards in line with each other, the pistons reciprocating therein, cross-rods fitted in said guides, a cylinder mounted upon said rods `intermediate the horizontal cylinders and adapted to be moved laterally to and fro by said pistons, means for supplying a motive fluid to the cylinders, and a pair of reciprocating pistons in said upright cylinder having crank connection with the drive-shaft, substantially as described.

2. In a multiple-cylinder explosive-engine, the combination of a supporting-frame, standards carrying guides at their upper and lower ends, horizontal cylinders mounted in said standards in line with each other, cross-rods fitted in said guides, a cylinder mounted upon said rods intermediate the horizontal cylinders, pistons formed integral with said upright cylinder on either side thereof, adapted IOC to reciprocate in said horizontal cylinders, means for supplying a motive fluid to the cyl- -iuders, and a pair of reciprocating pistons in said upright cylinder having crank connection with the drive-shaft, substantially as described.

3. In a multiple-cylinder explosive-engine, the combination of a su pportin g-frame, standards carrying guides at their upper and lower ends, horizontal cylinders mounted in said standards in line with each other, cross-rods Iitted in said guides, a cylinder J movably mounted upon said rods intermediate the horizontal cylinders, the pistons K reciprocating therein, a slotted bar L rigidly connecting said pistons, a crank-pin M projecting through said slotted bar, means for supplying a motive Huid to the cylinders, and a drive-shaft operatively connected with said c 'ank-pin, substantially as described.

4. In an explosive-en gine such as described the combination of a supporting-frame, standards carrying guides at their upper and lower ends, horizontal cylinders mounted in said standards in line with each other, the pistons reciprocating therein, cross-rods fitted in said guides, a cylinder slidably mounted upon said FLAVIUS IIAYOT.
